ABSTRACT:
A polyimide resin composition for sliding members which has high heat resistance and sliding properties and excels in wear resistance under sliding conditions at high PV values and which can keep low the rate of shrinkage due to crystallization treatment. The composition is made up of 100 parts by weight of resin composition comprising 50-90% by weight of a thermoplastic polyimide resin and 50-10% by weight of graphite obtained by graphitizing a non-phenolic resin material and containing 97% or more of fixed carbon; 5-20 parts by weight of tetrafluoroethylene resin; and 5-30 parts by weight of a powdery hardened phenolic resin.
